AbstractAbout AuthorsReferences
The influence of a poly-functional additive on the basis of sulfates of calcium and iron (carphosiderate) as a modifier for manufacturing magnesia concretes with a filler of metallurgical slag is considered. This concrete has improved physical-mechanical properties that are confirmed by methods of physical-chemical studies. The effect of the polyfunctional additive on the change in the mineralogical composition of the concrete obtained and on the formation of its micro-structure is established. The developed composition of modified magnesia concrete has a compressive strength value of 110 MPa. The softening coefficient of modified magnesia concrete is 0.92 that makes it possible to use it as structural material operating under wet conditions.
